If you are using NTLM or Negotiate auth it could be
<http://bugs.squid-cache.org/show_bug.cgi?id=3997> which was fixed in 3.4.12

If you are using delay pools it could be
<http://bugs.squid-cache.org/show_bug.cgi?id=2907> which was fixed in 3.5.3.

Otherwise you will need to get an strace of the running proxy when its
cycling like this to see what exactly its trying to do.
